I have been using Environment prepared in the previous article for about a year and a half.
Using pyenv-vertualenv, I encountered a problem that python 3 system could not be installed well, so I will describe the corresponding method.
An error that occurred when trying to use Python 3.5.2. An error that occurs because the version of pyenv itself is old and Python3.5.2 itself does not exist in pyenv.
test_py352 $ pwd #The directory you were working in
/Users/XXX/work/test_py352
test $ pyenv install 3.5.2
python-build: definition not found: 3.5.2
See all available versions with `pyenv install --list'.
If the version you need is missing, try upgrading pyenv:
brew update && brew upgrade pyenv
If you update Homebrew and upgrade pyenv according to the message that appears after you type the command, it will be solved.
test_py352 $ cd ~ #Move to home directory
$ brew update

An error that occurred when trying to update Homebrew.
$ brew update
Error: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. For example, upgrading
to OS X El Capitan has been known to do this. Some versions of the
"InstantOn" component of Airfoil or running Cocktail cleanup/optimizations
are known to do this as well.
You should probably change the ownership and permissions of /usr/local
back to your user account.
sudo chown -R $(whoami):admin /usr/local
The error was not resolved even if I followed the message that appeared after typing the command, so I resolved it by referring to this. * 1
$ sudo chown -R $(whoami):admin /usr/local

After the brew update, you will be prompted to regain permissions, so Execute the command according to the message
